Abstract

This research presented Active Force Control (AFC) as a control method which is applied to Automatic Turret gun (ATG) in ground combat vehicles This method compares the reference force conducted by actuator with actual force of the mechanical systems that arise due to disturbances. The advantage of AFC method is its ability to handle disturbances effectively without complicated mathematical calculations. The AFC method uses Crude Approximation (CA) in the internal loop controller AFC as inertia matrix estimator as an important part in the control loop. Simulation without load on the azimuth movement shows PID controller produces the best precision with MSE of 0 degrees while RACAFC and RAC method provide MSE 0.267 degrees. In simulation on the elevation movement, the RAC method showed the best results with an estimated MSE of the targets shot of 2.42 degrees, while the PID and RACAFC method are 2.5 and 2.46 degrees. When simulation is conducted with additional load RACAFC method gives the best precision with a MSE of 0.267 and 2:46 degrees, while the PID method was 4.24 and the 10.52 degrees. RAC method produces MSE of 0.7 and 2.87 degrees. With the added load the performance of PID controller decreases. In the experiment on the constructed rig, RAC and RACAFC scheme produce smoother movement trajectory and minimum oscillation compared to the PID controller. In loaded conditions these methods are able to maintain their performance. However, these three methods can still achieve a reference point with or without load in the end of travel time

Abstract

ABSTRAK Robot Automated Guided Vehicle (AGV) secara luas diterapkan di berbagai tempat seperti pabrikasi dan manufaktur yang telah menggunakan sistem otomatis, khususnya pada area pergudangan. Ferlib AGV merupakan robot pembawa barang yang didesain khusus untuk membawa dan memindah barang. Robot Ferlib AGV diciptakan untuk memenuhi kebutuhan para pekerja dalam sistem tata kelola pergudangan di industri terutama pekerjaan yang bergerak dalam bidang ekspedisi pengiriman barang. Pada saat beberapa robot berjalan di ruang atau daerah kerja yang sama, terdapat masalah yang mungkin terjadi dalam manajemen lalu lintas salah satunya adalah tabrakan. Penelitian ini bertujuan untuk membuat sebuah sistem yang dapat membuat robot menuju ke posisi yang diinginkan dan sebuah sistem yang dapat menghindari terjadinya tabrakan untuk diimplementasikan pada robot Ferlib AGV sebagai robot pembawa barang. Ada dua jenis konflik yang dapat menyebabkan terjadinya tabrakan yaitu Node Conflict dan Opposite Conflict. Robot mendeteksi konflik menggunakan sensor Position Sensitive Device (PSD) jenis inframerah. Untuk menyelesaikan konflik antar robot dimulai dari perencanaan jalur yang sesuai, dan dasar efektivitas tugas penjadwalan pergerakan robot. Hasil dari sistem ini telah mampu membuat robot Ferlib AGV sebagai robot pembawa barang yang dapat membawa barang menuju posisi koordinat berdasarkan posisi yang diberikan, serta dapat mendeteksi konflik dan melakukan penghindaran berdasarkan jenis konflik yang terjadi. ABSTRACT Automated Guided Vehicle System (AGVs) robots are widely applied in various places such as manufacturing and manufacturing that have used automated systems, especially in warehousing areas. Ferlib AGV is a freight robot specifically designed to carry and move goods. The Ferlib AGV robot was created to meet the needs of workers in the warehousing governance system in the industry, especially jobs engaged in the transportation and transfer of goods. When several robots run in the same work space or area, there are problems that may occur in traffic management, one of which is a collision. This study aims to create a system that can make the robot go to the desired position and a system that can avoid collisions to be implemented on the Ferlib AGV robot as a freight robot. There are two types of conflicts that can cause collisions, namely Node Conflict and Opposite Conflict. Robots detect conflicts using an infrared sensor type Position Sensitive Device (PSD). To resolve conflicts between robots starts from the appropriate path planning, and the basic effectiveness of the task of scheduling robot movements. The results of this system have been able to make Ferlib AGV robots as goods-carrying robots that can carry goods to coordinate positions based on the given position, and can detect conflicts and avoidance based on the type of conflict that occurs.
